To allwhomitmayconoern:. 1

Be it known that I, JAMES W. WEBB, a citizen of the United States, residing at Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented new and useful Improvements in Tools, of which the following is a specification.

This invention relates to a tool and has for its primary object to provide a com bination tool that may be more efliciently used.

An object of the invention is to provide means for allowing instant adjustment of the jaw members with the additional advan- I tage that the jaw member can be just as quickly locked in an adjusted position.

With these and other objects in view the invention will be better understood from the following detailed description taken in connection with the accompanying drawings wherein:

Figure 1 is a plan view of the tool.

Fig. 2 is an edge elevation.

Fig. 3 is a sectional view on the line 33.

Fig. 4 is a sectional view on the line 4& of Fig. '1. I

Again referring to the drawing illustrating one of the many forms in which my invention may be constructed the numeral 1 designates a stationary jaw member having formed adjacent one end a pair of ears 2, while adjacent its other end the same is provided with a screw operating e ement 8 and a nail removing element 4. Cooperating with the stationary jaw 1 is a movable jaw 5 slidably received between the ears 2 but held against complete dislocation by a pin 6 arranged to engage the ears when the jaw is at its limit of travel.

This jaw 5 is provided with a series of teeth 7 that are arranged to cooperate with a worm 8 rotatably supported by a lever 9. This lever 9 is pivotally connected to the ears 2 by a pin 10 so that the same may be swung toward and away from the aw membcrs so as to associate or disassociate the worm 8 with the teeth 7 From this construction it will be seen that when the lever 9 is thrown to its forward position as shown in Fig. 1, the worm 8 is completely dislocated from the teeth 7 so that the jaw 5 may be instantly adjusted. By throwing the lever 9 toward the jaw members the Worm will engage the teeth so as to lock the jaw member in its ad u sted position. The lever .1 provided with a tapering recess 11,

wedgedly engaging the elements so :that when the lever 9 is in looking position it will be held against accidental displacement.

A very important feature of my invention is that the jaw members may be instantly adjusted and locked in an adjusted position in a manner to allow subsequent movement of the worm 8 to give fine adjustment. It is of course to be understood that the invention may be constructed in various manners and the parts associated in other relations therefore I do not desire to be limited in any manner except as set forth in the claims hereunto appended.

Having described my invention, What I claim is:

1. In a tool, a gripping jaw provided with an elongated shank provided at its outer end with an inwardly directed and substantially rectangularly disposed element, said jaw being further provided with two spaced rearwardly extending ears, a lever pivotally secured between the ears so as to be movable toward and away from the shank, said inwardly disposed element of the shank being in contact with said lever when the lever is turned inwardly toward the shank so as to positively limit inward movement thereof and maintain the lever in approximate parallelism with the shank, a second jaw movable toward and away from the first mentioned jaw and provided with anelongated shank slidable between said ears and between the shank of said first mentioned jaw and the lever, the shank of said second jaw having its edge adjacent the lever toothed, and a. worm carried by said lever and adapted for cooperation with said toothed edge of the shank of the second jaw when the lever is in its innermost position.

2. In a tool, a gripping jaw provided with an elongated shank having at its outer end an axial projection and an inwardly directed and rectangularly disposed element, said jaw being further provided with two spaced rearwardly extending ears, a lever pivotally secured between the cars so as to be movable toward and away from the shank, said inwardly disposed element of the shank being in contact with said lever when the lever is turned inwardly toward the shank so as to shank slidable between said ears and between the shank of said first mentioned jaw and the lever, and having its edges adjacent the lever toothed, said lever being provided at its outer end with a reotangularly disposed elernent adapted to fit snugly over theelement of the shank of the first mentioned jaw and centrally slotted for reception of said axial projection to hold the shank and the lever against relative lateral displace- 10 JAMES W.
